(01'. 15-2302 7' "This invention relates toimprovements-in rollers particularly adapted for applying paintuniformly to surfaces and the principai objects of the invention are todevise an implement pre- 'sentingauniform pile coveredsurface which willroll smooth-1y over the surface to which the paint is to be applied andwill spread the paint uniformly over such surface, to provide asimpleand efiective means for manipulating said roller in theapplication of paint to a surface and to devise a structure which willpermit the easy and quick interchange of rollers;

f further object is to provide a formof roller which may be manufacturedeconomically so that it-may be discarded and replaced without unduecost. I

The principal featurecf the invention consists iii-spirally mounting alength of textile fabric ilpon an open-ended cylinder; mounting bearingsupports in the open end of said cylinder and rotatably securing saidbearing supports and cyl inder from the shaft extension'of a handle.

A.- further important feature consists the novel manner of constructingthe end closures and bearing supports for the cylinder" whereby ajournal member is secured centrally in a cup or disc adapted to intoand. sealthe ends of the cylinder.

-l'n the accompanying drawings Figure i is a plan view of apaint-applying in pleinent constructed in accordance wit'h thisintention.

Figure 2 is an end elevational view. Figure 3- is a longitudinal partmid-sectional and part elevational view of a roller and bearing supportconstructed in accordance with this 2 The terminal ends of the textilestrips may be firmly secured place in addition to. the adhesive by theuse of wire staples 4 which may be driven into the cardboard and willgripand hold the terminal ends of the strips. It" will be noted inFigure 1 that any line extending lengthwise of the cylinder parallel itsaxis will intersectthe Figure 4 is an elevational View of the insideface of one of the end closure caps and journal bearing.

In the construction of the device herein shown thepaint-appl-yi-ngrollerl is preferably formed of a plurality of substantially cylindricallaminations 2 of cardboard and on the periphery of this cylinder isspirally mounted a length or lengths of a suitable textile fabric 3which is preferably a short pile fabric which, because of the spiralwinding, presents a uniform cylindrical pile surface. The fabric ismountedupon the cardboard cylinder and secured by a suitable adhesiye sothat the spiral edges of the fabric strips abut snugly and there-will.be no definite line of demarcation which might cause a bumping effect ifthe textile material were joined in a straight line lengthwise of thecylinder.

' flow at the seam.

spiral sea-m of the fabric 3 atonly two points affording extensive areasof pile surface side of the scam in directionof such line and also inthe direction perpendicular to, the areas forming reservoirs" for paintstorage of sufiicient I capacity to aiiord feed of'paintt'o a surfacebeing coated to bridge said seam with undiminished In addition, theindividual hairs of the pile 3' adjacent the spiral seam will bend inthe direction of the pass and will tend to bridge said seam.

It will be understood that a cylinder such as described may be made inany desirable length and afterwards cut: into shorter lengths if desiredto facilitate manufacture.

Sheet metal discs 5 formed with flanges 6' to fit snugly within theinterior circumference of the cardboard cylinder are formed withoutturned end flanges T, the sheet metal of the outer flanges beingpreferably rolled inwardly to. avoid. raw edges of the metal beingexposed. These discs. when fitted into the ends of the cylinder havetheir end flanges! abut snugly against the ends of the cylinder.

The discs 5 are formed with circular central orifices and inserted intothese orifices are the 9 on the outward side which abut the outer faceof the disc; and said bushings are formed; with.

stepped shoulders a which extend through the holes in the disc and the.bushings are secured in place by deforming the edges of the shoulders '9to.- form 10 which overlap the inside face 01 the disc: and thus holdthe bushings securely in position- V It will be: understood of counsethat these end discs. 5 may be made. fromv a solid. section otcast ormachined metal if desired in which case the bushings would form.anintegral part of the disc but the construction described ispreferable. Y

A handle ll has mounted therein a rod I 2 oi circular cross sectionwhich is bentat right angles for approximately a length slightly longerthan half the length ofthe cylinder, being bent again at right angles toform a short length f3 which is formed with a right angle bend I 4providing a substantially-'U-shaped structure the-endremote 2,545,700 vlies from the handle ll being of a length to extend through thepaint-applying cylinder.

A collar I5 is rigidly secured on the rod which extends through thecylinder at a point adjacent to the bend i5 and abuts the bearingbushings in the cap inserted in one end of the roller formed by theflanged discs.

The outer end of the rod extends through and is journalled in thebushing in the disc at the opposite end of the roller and it is threadedto receive a suitable nut [6.

The roller is thus mounted on adequate journals at both ends andprovides a tool for applying paint to surfaces which may be handled withease and facility.

When it is desired to change the roller, either.

because of excessive wear or being allowed to dry with paint upon it orto use another colour of paint, it is simply necessary to remove the nut16 from the threaded endlof the handle rod and withdraw the rod from theend discs, The discs may then be pried loose from the end of thecylinder and inserted in the fresh cylinder, When thus inserted the rodend is slipped into place and the nut replaced and the device isagainready for use.

The spirally wound pile fabric mounted on journals in the mannerdescribed provides an exceptionally fine implement for applying paint tosurfaces and its ready removal and substitution can be accomplished atvery low cost.

What I claim as my invention is:

, l. A roller for applying paint comprising a cylinder open at the endsand having a textile paintapplying outer surface, circular memberspressed into the ends of said cylinder and having peripheral flangesgripping the interior of said cylinder and each formed with a centralorifice and an out-turned end flange projecting right angularly from itsperipheral flange abutting the adjacent end of the cylinder preventinginward movement of said members. journal bushings extending through andsecured in said central orifices in said members, said members formingboth the sole means of supporting said journals bushings within saidcylinder and the means maintaining separation of said journal, bushingswith said journal bushings secured to and removable with said membersfrom said cylinder, a rod having a handle extension removably androtatably mounted in said bushings, a shoulder carried by said rodabutting the journal bushing of one of the said circular members, and anut carried at the free end ofsaid rod and abutting the journal bushingof the other of said circular members effecting pressing of the circularmembers into the cylinder ends to grip said cylinder between saidout-turned flanges to locate said bushings within said cylinder and tosupcrt and hold said cylinder on said'rod.
